It is rumored that the new generation iPhone will have 16:9 aspect ratio either a 3.999 inch or 4.1 inch screen
which is perfect for you to play video on iPhone 5.
In order to beat competitors like Samsung Electronics Comp.,Ltd., Apple aims at making larger phones. CEO Steven P. Jobs called larger handsets "Hummer" phones, remarking "you can't get your hand around it" and "no one's going to buy that".
Various news roundups indicate that that Apple is cooking up a larger smartphone for its sixth generation iPhone and iPod Touch. Report fromMacRumors said that the display will have a diagonal of 4.1-inches and that "the display would be taller than the current model". 9 to 5 Mac agrees an aspect ratio change (from 3:2 to 16:9) is incoming, but it argues that the new display will be 3.999 inches in diagonal (1.9632 in. wide x 3.484 in. tall). And another piece of news states that Apple will release a 7-inch "Mini iPad" later this year.
Well rumors are rumors after all. Maybe
later this year, we will figure out what the new generation iPhone looks like
and whether there is iPad Mini.
